ABSTRACT
A novel process to produce a H2-rich syngas from high moisture-containing agricultural waste digestate is proposed. This combines the use of hydrothermal carbonization (HTC), dewatering, pyrolysis, and catalytic reforming. Due feature moisture content in digestate, effect HTC dewatering on performance interest, four scenarios were considered. Furthermore, three pyrolytic temperatures chosen understand pyrolysis conditions produced syngas. life cycle assessment was conducted investigate environmental impact proposed process. Results show that application technology, increases efficiency, produces less one ton lowers cumulative energy demand negative carbon emissions. When technology used, yield promoted but H2 concentration reduced. The CO molar ratio reaches maximum value 9.2 when using 450 ˚C temperature, by only HTC. combining it results highest smallest relative CO2 equivalent emissions treating dry digestate.
